Recently, I don't know why but on my cart and checkout page (I'm using Cart66), if I click on show details to see the data of the form, this message appears:
Warning: nl2br() expects parameter 1 to be string, array given in /nfs/c10/h05/mnt/141495/domains/idealinput.com/html/wp-content/plugins/gravityforms/common.php on line 3824
Here is a screenshot: http://i44.tinypic.com/2uixhrb.png
I know this is not a theme conflict as I tested it with other themes and was still there. Any solution?
Thanks a lot and have a great day!
